. To all whom t may concern:

Be it known that we, PAUL HEINRICH ERNST RMER and Monrrz PAUL MEIssNnR, of Ghemnitz, in the Kingdom of Saxony, German Emy pire, have invented anew and useful Improvement in Machines for Automatically Folding s Fabrics and Inserting Pressing Boards Between the Folds-thereof; and the following is declared to be a full and exact description of s Io the same.

This invention relates to the machine in which pressing boards, pressing -paper, or cards are automatically inserted between the folds of fabric. For this purpose a table is arranged which is kept in its highest position by a spring, and which table descends in proportion to the weight of fabric and pressingboards with which it becomes loaded. Above this table two rollers travel, working in hori- 2o zontal guides arranged above the table and near the sides of the same. Between these rollers the fabric enters, which is spread over the table into regularly-arranged folds by the travelingrollers. There are two sets of pinchers ar- 2 5` ranged in combination with the above-mentionedrollers and traveling with them,which pinchers are opened and closed at proper intervals. At each change in the direction of travel of said rollers one pair of pinchers is closed andseizes 3o or takes hold of a pressing-board, drawing the same along with it. As the travel of the rollers is completed in one direction, the same pair of pinchers is opened, thereby releasing the press- A ing-board, whichmis deposited upon the fabric. 3 5 At the Sametime the other pair of pinchers at theother side of the rollers is closed, in orcrank c.

boxes facing the machine are open, to `allow the box to be movedtoward one or more pressing-rollers, against which thepressing-boards come into contact, and are kept in a vertical position by such rollers. With each box a mechanism is combined by which a pressingboard at the proper instant is raised and pushed into a curved guide, thereby changing its path or movement from perpendicular to horizontal, and the board being held is4 ready for its protruding end to be seized by the above-mentioned pinchers at the proper instant and be drawn out of the curved guide and deposited upon the last-laid fold of fabric.

The machine is represented in side view (partly in section) in Fig. l and in plan in Fig.

2. The other gures show the details, and are separately referred to.

a is the table, carried by a central rod, I), which may ascend or descend within a tubular column, b3, so that the table supported by a spiral spring, b4, may descend according to the weight of the fabric and boards deposited thereon. Above the table a and at both sides of it two horizontal guides,` a3, are arranged, in which two rollers, ff', travel, which fold the fabric on the table a. The entrance of the fabric between such rollers is indicated by the vertical arrow, Fig. l. The rollers are mounted in end bearings that are common to both,which bearings are moved by the lever c, which is slotted at the upper end, and is moved by the rod d, to which motion is imparted by the The lever c has its fulcrum c2 at its lower end.

The arrangement, construction, and mode of working of the two sets of pinchers at both sides of the rollers ff are more clearly to beV seen in the partial section, Fig. 3, and plan, Fi 4. It is supposed that in the position illustrated the parts travel in the direction of the arrow, Fig.3, so that the left-hand-side pinchers are closed and I draw along a pressing-board, while the right-handfside pinchers are open,'and will be closed at the completion of this movement in order to seize a pressing-board. A l The end bearings that slide in the guides a are connected by the cross-bars b.

Upon each of these bars b there are two jaws, one near each end of the bar and projecting outwardly, so as to be adapted to grasp and draw into place the boards from rst one end of the machine and then the other. rlhe respective jaws are alike and operate together in pairs, the parts standing in opposite positions at the respective ends of the shaft. We will describe one jaw and the mechanism connected with it.

n Upon the bar b there is a fixed jaw, a, that proj ects therefrom nearlyhorizontally. To this fixed jaw is hinged the moving jaw c3, that is made as a bent lever, the moving jaw ci extending horizontally beneath the jaw a', the 'other portion or lever end, c, standing nearly vertically. There is a spring, cZ, above the fixed jaw a', the upper part of which spring acts against the vertical portion c of the moving jaw c3, tending to close the same. When the board is grasped by the jaws, the pressure of the spring d causes such jaws to retain their hold of such board until it is drawn entirely over the layer of fabric. At this moment the jaw is opened by the following means: The rocker-shaft 7c is above the bar b', and has at one end a finger, 7L, that is acted upon by the spring-boltZ or Z as the carriage is moved, and this finger h turns the rocker-shaft k, and

by the cam Z' opens the moving jaw c by pressing against the back of the lever end o. The spring around the spring-bolt Z or Z allows it to rise if the end of the finger h comes in contact with the inclined end of the spring-bolt Z or Z on the return movement. There is a spring-bolt, e, that is supported in bearings on the bar b', and it has an arm at its end which is adjacent to the back of the lever end c of the moving jaw 1 Vhen this moving jaw is opened by the cam t', rocker-shaft 7c, finger h, and spring-bolt` Z or Z, as aforesaid, the spring of the bolt e gives it an endwise movement and brings the arm at its end in behind the lever end c of the moving jaw c3, so as tohold that jaw open, and it remains in that position until the carriage and bars b have nearly reached the extreme of their movement in the opposite direction, at which time the open jaw has reached the end of the board that is to be drawn in. At this moment the end of the bolt e runs against the incline g or g', and its arm is carried from behind the lever c ofthe open moving jaw c3 and liberates such jaw, so that the springd closes and the pinchers grasp the board and move it with the carriage, as aforesaid. Each closing of one pair of pinchers has for its result the seizing of a press-board, while the opening of that device deposits a press-board on the fabric. The boards are vertically arranged within the boxes m,running on wheels r* and rails r. The boxes are pressed toward the middle of the machine by the weights m', so that the lpressing-boards always bearv against the roller n. The' upper part of the boards bear in the same manner against the friction-disks o. If these friction-disks 0 are turned or revolved by means of the bevelwheels p p', they Will by friction cause the pressing boards in Contact with them to rise a certain distance, and at the same time the horizontal rod r will come underneath the loweredge 0f the board raised. The rod r is suspended by cords that pass over the rollers u, and are attached to the upper ends of the levers t. The lower ends of these levers t are connected with the shaft t3, and this shaft is rocked and the rod r drawn upwardly at the proper time to lift the board and cause its upper end to enter into and pass through the bent or curved guide v, so that the board Vprotrudes from the guide with its end horizontal, and may be seized by the, pinchers at the proper instant. The pressing-board by this movement is changed from a perpendicular to a horizontal position. The levers s and s are connected to the horizontal rock-shaft t3, andv transmitted from a vertical position into a A horizontal one.

The combination, with the table which is adapted to descend by the weight of fabric upon it, of the traveling rollers and pinchers, the movable vertical side boxes containing the pressing-boards, constructed so as to support or carry the pressing-boards in a vertical position, and mechanism for operating said pinchers and for raising said boards automatically and alternately from the vertical boxes, and for changing their position from a vertical to a horizontal one in order to be seized by the pinchers, substantially as set forth.
